ARRI Signature Prime Lens 15mm / T1.8 Feet Scale

Organic Images Full of Life and Emotion

The ARRI Signature Prime 15mm/T1.8 is a cornerstone of the large-format lens series, designed to deliver organic, emotionally resonant images. While these optics exemplify state-of-the-art precision, they are engineered to gently soften and texturize the large format with natural skin tones and creamy bokeh. The fast T1.8 aperture facilitates a shallow depth of field, while the smooth focus fall-off gives subjects a heightened presence within the frame.

Advanced Magnesium Construction and LDS-2 Technology

The ARRI Signature Prime range is the first cine lens series to feature machined magnesium lens barrels, making the 15mm lens incredibly lightweight and robust. It incorporates ARRI’s next-generation LDS-2 Lens Data System, featuring high data rates and absolute encoders for fast initializing. LDS-2 extends the possibilities of lens metadata and is the new standard for modern production workflows.

Universal LPL Mount Compatibility

Equipped with the LPL (Large Positive Locking) lens mount, this lens is a key element of ARRI’s large-format camera system. The wider diameter and shorter flange focal depth allow LPL lenses to remain compact and lightweight while maintaining a fast T-stop. ARRI LPL mounts are available for ALEXA 65, ALEXA LF, ALEXA Mini LF, ALEXA Classic/XT/SXT, ALEXA Mini, and AMIRA cameras. Additionally, third-party LPL mounts for cameras and director's viewfinders ensure these lenses can be used universally across various platforms.
